The evidence so far is that traffic has dropped across the wider area, and active travel has increased significantly. EDG is the exception and one of the few perimeter roads where there does seem to have been an increase in traffic. That needs to be addressed - but the evidence on the Dulwich LTN, and on LTNs more generally, is that they reduce car use and increase active travel. I also expect (and again, evidence from similar, longer standing schemes would support the expectation) that modal shift will continue over time - possibly even pick up momentum. I know a number of people (myself included), who have changed their behaviour since the introduction of LTNs and further encouraged by the pending ULEZ extension, are looking get rid of their cars altogether. Of course this is anecdotal, and time will. What will definitely not improve upon the previous situation is returning everything to the previous state. By definition.
